HERBERT R. BLISS, OF NIAG AILA FALLS, NEW YORK.

HETHQD OF SEALING FIBER SEIPPING GASES.

To all whom it may do Be it known that human B. Buss, a citizen of the United Statesfiesiding at Ni agara Falls,-in the county of Niagara and State of New York, have invented certain new and useful Improvements in Methods of Sealing Fiber shippin Cases, of which the following is a speci cation.

This invention relates to a method of sealing shipping cases. One of the forms of fiber cases that has met with considerable favor is the recessed end case. This is a case made from a single blank which is folded upon itself to provide four side walls and then lapped at one corner and wire-stitched. A sort of inverted cover is then inserted in the bottom of this side wall structure and stitched to the side walls along the four sides of the flange. The case is then filled and the top cover inverted and stitched with wire stitches in the same way as the bottom. One of the objections to this form of case has been that it has always had to be packed at the end. With some classes of goods it is very much more suitable to pack them through one of the long sides of the case. It has never been possible to so pack these cases.

The object of the present invention is to provide a new method of manufacturing and sealing these cases so that they can be packed from the long side.

In the drawings,- a

Fig. 1 is a view of the blank for the side walls.

Fig. 2 is a plan view of the cover blank.

Fig. 3 is a section on the line 3-3 of Fig l.

ig. 4 is a section on the line 4-4 of Fig. 2.

Fig. 5 shows the blank folded with the inverted and inset covers stitched at each end on only three sides.

Fig. 6 is a section on the line 6-6 of Fig. 5.

Fig. 7 shows how the case is finally sealed after having been packed.

Fig. 8 is a sectlon on the line 8-8 of Fig. 10.

Fig. 9 is a section on the line 9-9 of Fig. 10.

Fig. 10 is a perspective of the sealed case.

The blank is diflerently formed from the ordinary blank used in this type of case. Ordinarily the blank is cut with four side walls of full size with a short overlapping 6n away a, 1920. Serial noiseasas.

flap at one end of the blank. This flap is turned over the side wall at one corner and wire-stitched thereto. As already explained, the end covers are then inverted and inset and stitched around the four sides of the flanges. The box is made on the ordinary stitching machine. No difliculty in using an anvil for clinching the stitches is met with when this method of manufacture is adopted. With a blank such as shown in Fig. 1, the same is folded along the usual creases which are clearly evident in the drawings, and then both ends are inverted and inset as shown in Fig. 5 and stitched only on three sides of the same. This is clearly apparent in Figs. 5 and 6. The cover and sides opposite the flaps are left open. This allows the case to be packed from the long side. The flaps are then overlapped as is shown in Fig. 7 and the blade anvil there shown inserted under the flaps, or rather, the box is really slipped over the blade anvil. Wire stitches are then taken along the line of the overlappin flaps and finally the overlapping flaps are a so stitched to the one remaining cover flange in each cover that has been left unstitched. This completes the box and very securely seals the same.

What I claim is:

1. The method of constructing and sealing a recessed end fiber shipping case, which comprises folding a rectangular blank to form the bottom and two side walls and the overlapping top flaps, slotting a pair of rectangular end blanks at the corners and scoring each with a single rectangular scoring figure parallel with the four edges to form with the said slots four flanges, the setting of the end blanks the complete depth of the flanges into the folded main body blank and causing the free edges of the flanges to register with the edges at the end of the main body blank and folding in the ends of the flanges at the corners, the running of a line of stitches through the, flan es and the ends of the bottom and side wa ls, and sealing the case by taking a continuous H run of stitches on the overlapping cover flaps in which the center bar of the H runs along parallel with and near the meetin edges of the flaps and the two uprights o 'the H run'along the ends of the flaps and through the flanges of the end blanks.

2.
